Epitaxy: Not Just For PMOS Anymore

Epitaxy: Not Just For PMOS Anymore
by Paul McLellan on 07-25-2013 at 2:25 pm

At Semicon I met with Applied Materials to learn about epitaxy. This is when a monocrystalline film is grown on the substrate which takes on a lattice structure that matches the substrate. It forms a high purity starting point for building a transistor and is also the basis of the strain engineering in a modern process.

Since holes… Read More

System Reliability Audits
by Paul McLellan on 07-25-2013 at 12:09 pm

How reliable is your cell-phone? Actually, you don’t really care. It will crash from time to time due to software bugs and you’ll throw it away after two or three years. If a few phones also crash due to stray neutrons from outer space or stray alpha particles from the solder balls used in the flip-chip bonding then nobody… Read More


From Layout Sign-off to RTL Sign-off

This week, I had a nice opportunity meeting Charu Puri, Corporate Marketing and Sushil Gupta, V.P. & Managing Director at Atrenta, Noida. Well, I know Sushil since 1990s; in fact, he was my manager at one point of time during my job earlier than Cadence. He leads this large R&D development centre, consisting about 200 people… Read More


Any MIPI CSI-3 Host IP Solution for SoCs Interfacing with Sensors?

Any MIPI CSI-3 Host IP Solution for SoCs Interfacing with Sensors?
by Eric Esteve on 07-25-2013 at 4:37 am

For those taking a quick look at the various MIPI Interface specification, the first reaction is to realize that they will have to look at MIPI more closely, and that it will take them longer than expected to make sure they really understand the various specifications! Let’s start with the PHY. One specification defines the D-PHY,… Read More


Semicon: Multiple Patterning vs EUV, round #2

Semicon: Multiple Patterning vs EUV, round #2
by Paul McLellan on 07-24-2013 at 9:00 pm

Round #1 was here.

In the EUV corner were Stefan Wurm of Sematech (working on mask issues mostly) and Skip Miller of ASML who are the only company making EUV steppers (and light sources, they acquired Cymer).

You may know that the biggest issue in EUV is getting the source brightness to have high enough energy that an EUV stepper has … Read More

EDA tool development is always pushing the boundaries, driven in part by bigger, faster chips and more complex IP. For several years now, the trend has been developing tools that spot problems faster without waiting for the “big bang” synthesis result that takes hours and hours. Vendors, with help from customers, are tuning tools… Read More


Metastability Starts With Standard Cells

Metastability Starts With Standard Cells
by Daniel Nenni on 07-24-2013 at 8:05 pm

Metastability is a critical SoC failure mode that occurs at the interface between clocked and clockless systems. It’s a risk that must be carefully managed as the industry moves to increasingly dense designs at 28nm and below. Blendics is an emerging technology company that I have been working with recently, their MetaACERead More

The FPGA Blob is Coming…
by Luke Miller on 07-24-2013 at 5:00 pm

I never understood when I was a kid how ‘the Blob’ could actually catch someone but it sure did. It caught the unsuspecting, the off guard. I mean you’d have time for a soda and shower if you saw it on your road. And no, your manager is not the Blob; don’t think like that, it’s always his boss. The blob comes to consume the worker who was unaware… Read More


TSMC Q2 Results: Up 17%; 20nm and 16nm on track

TSMC Q2 Results: Up 17%; 20nm and 16nm on track
by Paul McLellan on 07-24-2013 at 10:47 am

TSMC announced their Q2 financial results yesterday. Revenue was $5.2B (at the high end of guidance) with net income of $1.6B. This is up 17.4% on Q1 and up 21.6% year-to-year. Gross margin is up too, at 49% which is up 3.2 points on Q1 and 0.3 points year-to-year. As usual the financial results are not directly that interesting since… Read More

Scott Fitzgerald is supposed to have said “the rich are not like other people” to Ernest Hemingway (he didn’t). In the same way, processors are not like other blocks, and not because they have more gates (they don’t). However, special approaches to optimizing processors are important because the clock… Read More
